Hi !
I hate to work on this board, no fan spin = no fun. The board was liquid damaged, came here with no image. I refurbished the LCD connector that had minor corrosion and replaced the flex, LCD came back. When LCD went back, I discovered there was no KB no TP, the TP flex was damaged so I changed it too and now I have KB and TP, access to session and battery detection & charging.
The last problem is that the Mac is running really slow, I ultrasonic cleaned the board, no change. I tried with another battery and an other LCD, same thing. I found that PPBUS_G3H is a bit higher as expected at 8.75V and it's probably a clue but I don't know how to interpret this.
Thank you for you help and ask me anything that I forgot on this description.
